We wanted to glob all the hits from Google Homepage Modules into a single category so instead of being presented with a long list of equivalent subdomains (33.gmodules.com/ig/ifr, 82.gmodules.com/ig/ifr, http://35.gmodules.com/ig/ifr, etc) I would see a single item, something like this... ##.gmodules.com/
Unfortunately the data filters can only be applied to incoming data. They do not have any effect on the data that has already been collected. So if we see something in our report that we would like to change and set up a filter accordingly, it will likely be a day later before we get to see if the results are what was wanted.
Will we eventually be able to apply filters to the data already collected? Or at least see a preview of what the results would be? Google only knows.
